Is the major chord heard when a Mac boots up a reference to "A Day in the Life"? Also-- there's a complete transcription of the Beatles output published by Hal Leonard. For the orchestral gliss from "A Day in the Life" there is an ascending line drawn on a single staff, and the staff is titled "orchestra". I thought that was pretty funny.
